Had been meaning to post this, not really an issue but an interesting anomoly. It's happened a few times and I always forget to check what the mission is, but it's a partol variant that's actually a shipyard/defense in a black hole terrain.
The planet sometimes "slips" into the blackhole, which is kinda wierd/cool. It doesn't actually explode, but you hear that thunderous sound of damage being taken by it and the damage is "incredible"
attached is screencap of volleyinfo. The damage does kill off marines on the planet surface, but it's a shipyard def type mission so no undue advantage per se... interesting too cuz the blackhole is inside the planet and the gravity pull on ships approaching the planet is neat to watch.....
